PROCESS OF OBTAINING CHLOR-ACETIC ACID.

Specification of Letters Patent.

Patented Sept. 28, 1909.

No Drawing. Original application filed May 1, 1907, Serial No. 371,237. Divided and this application filed March 2, 1908.

To all whom it may concern:

Be it known that I, Gnonons IMnnR'r, a citizen of the German Empire, and resident of Nuremberg, Bavaria, Germany, have invented a new and useful Process for Obtaining Chlor-Acetic Acid, of which the following is a full, clear, and exact description.

' rapid vaporization.

The process may be expressed by the fol lowing equation For example, if 100 kg. of di-chlor-ethoxy- Serial No. 418,898.

ethylene are heated with 400 kg. of water by the aid of a return-flow cooling apparatus, until the mixture has just turned ll0-- mogeneous, and the resulting solution is evaporated in oacuo, the chlor-acetic-acid will remain in crystallized form.

I claim as my invention 1. A process of producing chlor-acet-ic acid which consists in heating di-chlorethoxy-ethylene with a surplus of water until the result is a homogeneous solution and subsequently rapidly evaporating.

2. A process of producing chlor-aceticacid which consists in heating di-chlorethoxy-ethylene with a surplus of Water, until the result is a homogeneous solution and subsequently evaporating in a vacuum.

In testimony whereof I afiix my signature in the presence of two witnesses.
